### TITLE: FLIGHT CONTROLS - SPOILER SERVOCONTROL - CHECK OF THE HYDRAULIC LOCKING FUNCTION **CONF ALL MODIFICATIONS None REASON/DESCRIPTION/OPERATIONAL CONSEQUENCES During a post maintenance check flight, an airline identified that 5 Spoiler Servo Controls (SSC) MZ series had lost their Hydraulic Locking Function. The failure was confirmed during shop investigations at LIEBHERR facilities: a seal involved in the locking function was found sheared the same way in the 5 Servo Controls. All Operators Telex (AOT) A330-27A3185 and AOT A340-27A4181 dated 04 January 2012 were issued to request a one-time inspection of the Hydraulic Locking Function as per the new AMM Task 27-64-00-710-802 on all MZ Spoiler Servo Controls. Currently there is no repetitive maintenance task to check the Hydraulic Locking Function of the Spoiler Servo Controls (whatever the PN). The aim of this Service Bulletin is to introduce a repetitive maintenance task to check the hydraulic locking function. Due to hydraulic power generations re-configuration laws, it is more probable to lose the Blue or Yellow pressure in the event of an engine failure at take-off (one engine pump on Blue and Yellow circuits, two engine pumps on Green circuit). Consequently, to preserve the low probability of a spoiler extension at take-off in case of engine failure, and in accordance with Airworthiness objectives, the accomplishment of this Inspection Service Bulletin (ISB) requires performing the test of the Hydraulic Locking Function as per AMM Task 27-64-00-710-802 on Spoiler Servo Controls installed on Blue and Yellow Hydraulic Circuits, that is to say: positions FINs 14CS1, 15CS1, 16CS1, 18CS1, 14CS2, 15CS2, 16CS2 and 18CS2 within 48 months after aircraft first flight or within 24 months after ISB issue, whichever occurs the latest, and then at intervals not exceeding 48 months.

F. APPROVAL The technical content of this document is approved under the authority of Design Organization Approval No. EASA.21J.031. If an aircraft listed in the effectivity has a modification or repair embodied that is not of AIRBUS origin, and which affects the content of this Service Bulletin, the operator is responsible for obtaining approval by its airworthiness authority for any adaptation necessary before incorporation of the Service Bulletin. G. MANPOWER The manpower estimates given in this Service Bulletin are based on the direct labor cost to do the work. These estimates assume that the work will be done by experienced personnel, and may need to be revised upwards to suit operator’s circumstances. The estimates do not include the time to prepare, plan or inspect the work. Manufacture and procurement of parts and tools, drying times for paints, sealants, etc., and general administration work are also not included. For an explanation of the manhours and elapsed time, refer to the Gantt Chart given in Appendix 01 - Elapsed Time Assumption

3. ACCOMPLISHMENT INSTRUCTIONS Task 274188-832-801-001 - Operational Test WARNING: MAKE SURE THAT YOU OBEY ALL THE WARNINGS AND ALL THE CAUTIONS INCLUDED IN THE REFERENCED PROCEDURES. CAUTION: ALWAYS OBEY THE PRECAUTIONS THAT FOLLOW TO KEEP ELECTRICAL WIRING IN A SATISFACTORY CONDITION (ELECTRICALLY AND MECHANICALLY SERVICEABLE). WHEN YOU DO MAINTENANCE WORK, REPAIRS OR MODIFICATIONS, ALWAYS KEEP ELECTRICAL WIRING, COMPONENTS AND THE WORK AREA AS CLEAN AS POSSIBLE. TO DO THIS: - PUT PROTECTION, SUCH AS PLASTIC SHEETING, CLOTHS, ETC; AS NECESSARY ON WIRING AND COMPONENTS. - REGULARLY REMOVE ALL SHAVINGS, UNWANTED MATERIAL AND OTHER CONTAMINATION. THESE PRECAUTIONS WILL DECREASE THE RISK OF CONTAMINATION AND DAMAGE TO THE ELECTRICAL WIRING INSTALLATION. IF THERE IS CONTAMINATION, REFER TO ESPM 20-55-00. NOTE: The accomplishment instructions of this Service Bulletin refer to procedures included in other AIRBUS documents. When the words ’refer to’ are used and the operator has an accepted alternative procedure, the accepted alternative procedure can be used. When the words ’in accordance with’ are included in the instruction, the procedure in the AIRBUS document must be used. NOTE: The access and close-up instructions, not comprising return to service tests, in this Service Bulletin do not constitute or affect the technical intent of the Service Bulletin. Operators can therefore, as deemed necessary, omit or add access and/or close-up steps to add flexibility to their maintenance operations as long as the technical intent of the Service Bulletin is met within the set parameters. NOTE: Manual titles given in the accomplishment instructions are referred to by acronyms. Refer to paragraph 1.J., References, for the definition of acronyms. NOTE: This Service Bulletin is classified mandatory or expected to be classified mandatory by an Airworthiness Directive (AD). The paragraphs 3.C. and 3.D. in these accomplishment instructions are Required for Compliance (RC) and must be done to comply with the AD. Other paragraphs are recommended and may be deviated from, done as part of other actions or done with accepted methods different from those given in the Service Bulletin, as long as the RC paragraphs can be done and the aircraft can be put back into a serviceable condition. NOTE: The purpose of flow charts are for information only to show the various Inspection/Repair phases described in this Service Bulletin.
